Using this Chelsea FC backpack is a breeze. Just unzip the main compartment's large double - zipped opening to put in your books, clothes, or other items. Use the front zipped pocket for small things like keys or cards. When carrying it, adjust the padded shoulder straps to your comfort. If you want, you can also use the carry strap. As for maintenance, simply wipe it with a damp cloth if it gets dirty. Avoid using harsh chemicals as they might damage the club crest and the fabric. Don't overstuff the backpack to keep its shape. Store it in a dry place when not in use.
